9 Claims.

This invention relates to windows of the scalled awning type, wherein a plurality of sashes are pivotally mounted one above the other and are coupled together in such a manner that an opening or closing movement of one of the sashes, controlled by a suitable operating means, will simultaneously open or close the other sashes.

The invention has for its primary object, the provision of a simplified structure in which the various operating parts are housed and protected in the window frame and by the manipulation of a hand-operated crank, the several sashes will be simultaneously opened or closed.

The invention further contemplates the provision of improved sash-operating means occupying but little space and centrally located on the window frame; it contemplates the provision of means by which balanced operation of the window is attained, and it results in the securement of operating results superior to those resulting from other structures known in this art.

With these and other objects to be hereinafter set forth in view, I have devised the particular arrangement of parts hereinafter set forth and more particularly pointed out in the claims appended hereto.

In the accompanying drawings forming a part hereof, in which an illustrative embodiment of the invention is disclosed, Fig. 1 is a vertical sectional View through a window constructed in accordance with the invention, with the sashes thereof shown in closed position; Fig. 2 is a vertical sectional view through the window with the sashes shown in closed position, the section being taken substantially on the line 2-2 of Fig. 3, looking in the direction of the arrows; Fig. 3 is a sectional View taken on the line 3-3 of Fig. 2, looking in the direction of the arrows; Fig. 4 is a sectional view through one of the anchorage plates for the lower pivot of the Sash links, the view being taken on the line ll-ll of Fig. 1; Fig. 5 is a view of the lower part or sill of the window frame, looking at the inner side of the same, with parts broken away, and with other parts in section, to disclose construction; Fig. 6 is a longitudinal sectional view through the sash-operating mechanism; Fig. 7 is a sectional view through the sash-operating gearing and associated parts, and Fig. 8 is a sectional view through the lower member or sill of the window frame and through the torsion sleeve and operating shaft.

Referring to the drawingi generally indicates the frame of the window, which is preferably the so-called box type and is composed of metal. It is of rectangular form and channel shape in I lower part of Fig. 1.

cross section and thus includes an outer wall 2 of considerably greater length than an inner wall 3, both walls being connected by the integral rear web 4. The outer wall 2 includes an inturned edge flange 5 against which a ilange 6 on the sashes I and 8 abuts, as seen, for example, at the The inner wall 3 of the frame is also provided with an inturned edge flange 9 against which the inner portion of the sashes abut when the sashes are in closed posil tion, as shown at the top and bottom of Fig. 1.

When the sashes are in their closed position, as seen in Fig. 1, it will be noted that the frame presents rearwardly of the sashes, a channel I0 Within which a vertically-movable slide bar II is confined, said slide bar maintained in the channel and being restrained from forward movement by means of a plurality of rollers IIa rotative on pivot pins I2 secured in the outer walls 2 of the vertical sides of the window frame I. Secured to each side edge of the sashes 'I' and 8 is an arm I3 which is formed with an offset outer end I4, pivotally attached at I5 to the slide bar I I. Also pivotally attached at I6 to each side edge of each of the sashes 'I and 8 is one end of a link II which has its opposite end pivotally attached at I8 to an adjustable anchorage plate I9 slotted as at 20 to receive the attaching screws 2| extending through the inner anges 2 of the window frame. This slotted attachment enables a precise adjustment of the several sashes to accurate closing position.

It will be noted that in the structure described, the pivots I5 which attach the sashes to the slide bar, and the pivots I8 which attach the lower ends of the links I1 to the window frame, are not located between the edges of the respective sashes and the frame, but are in fact located in and confined by the channel II] in the frame wholly to the rear of the sashes regardless of whether the sashes are in open or closed position, the window frame being of sufficient depth to enable these pivots to be housed within it to the rear of the y sash frames.

vertically reciprocating the slide bar ll clearly shown in Figs. 5 to 8 inclusive, will now be described.

Located in the lower horizontal channel 22 of the window frame is a lengthy rotating or rocking shaft 23 constituting the sash-operating member and having movements which cause raising and lowering of the slide bar and resultant opening and closing movements of the sashes. Said shaft is rotative Within a torsion tube 24 of considerably greater diameter than the shaft 23. Said tube 24 is secured to parts of the frame by the fastening screws 25, and mounted within the tube are spacing bushings 26 and 21 in which the shaft 23 is rotative. The outer bushings 26 are provided with bearings 50 through which the shaft 23 passes and in which the same is rotative.

Secured at a central or middle point on the shaft 23 is a gear 28 .which meshes with and is rotated by a gear 29 having its axis 3G arranged vertically and rotative within a housing 3i secured by the fasteningv screws 32 to the frame and which screws also enter and hold the bushings 21 in position within the tube '24.

The gear 29 is maintained on spindle 39 by;

closure plate 45 held in place by the screw 4E as shown in Fig. '1. The tube 24 is cut away as required to enable the gears 28 and 29 to interengage, as clearly shown in Figs.V 6 and 7. The

gear 29 is rotated by a worm 33 secured on a.`

shaft 34 having an end protruding out of the housing 3i and secured by the coupling 35 to the handle or operating crank 36.

Fastened to each end of the shaft 23 is a radially-extending arm 31 pivoted at 38 to one end of a link 39, having its upper end pivotally attached at 40 to one of the slide bars H. Through the arrangement described, it will be apparent that by rotative movement of the crank or handle 36, the shaft 23 will be rocked or rotatively moved, and such movements will be transmitted to the slide bars Il bymeans of the arms 31 and links 39. As the slide bars are moved up or down the same will cause the sashes to be moved accordingly to open, closed or intermediate positions.

The location of the operating means at the center of the operating shaft 23 results in a balanced arrangement whereby the operation of the sashes to open, closed or intermediate positions is smooth and effectively done. The enclosure of the operating shaft 23 in the `relatively large diameter torsion tube adds strength and rigidity to and prevents deformation of the operating shaft 23, and the location of the slide bars, the pivot points for the sashes, connecting links and operating links to the rear of the sashes within a bcx-line window frame of substantial thickness enables the various parts of the structure to be made relatively large and strong and results in a window of very long operating life.

While the window described is shown as having two superimposed sashes, it will be understood that it is merely illustrative as the same may be made with a greater number of sashes if required.

Having described one embodiment of the invention, it is obvious that the same is not to be restricted thereto, but is broad enough to cover all structures coming within the scope of the annexed claims.
